Crystallization behavior of random ethylene-butene copolymers modified with organic peroxide
(Elsevier Science, 2012-01-02)
The effect of molecular cross-linking on the crystallization of random ethylene-1-butene copolymers obtained from hydrogenation of model polybutadiene was studied by means of differential scanning calorimetry. The copolymers ...
Calcium oxalate crystal production and density at different phenological stages of soybean plants (Glycine max L.) from the southeast of the Pampean Plain, Argentina
(Wiley Blackwell Publishing, Inc, 2016-11)
Glycine max L. (soybean) is one of the major crops of the world. Although the process of biomineralisation has been reported in some organs of soybean, we now report the description and quantification of calcium oxalate ...
Comparison of optical properties of thermally reversible light scattering films consisting in dispersions of polystyrene/naphthalene domains or polystyrene/liquid crystal (EBBA) domains in epoxy matrices
(Springer, 2007-01)
Thermally reversible light scattering (TRLS) films are materials that can be reversibly switched from opaque to transparent states by varying temperature. TRLS films containing different types of dispersed domains in an ...
Crystallization behavior of poly(3-hydroxybutyrate) nanocomposites based on modified clays: Effect of organic modifiers
(Elsevier Science, 2012-09)
Isothermal and non-isothermal crystallization kinetics of nanocomposites of poly(3-hydroxybutyrate) (PHB) with 4 wt% of montmorillonite Cloisite®Na+ (CNa+) and chemically modified clays Cloisite®15A and 93A (C15A and C93A) ...
Reversible breaking and forming of Metal-Ligand coordination bonds: Temperature-Triggered Single-Crystal to Single-Crystal transformation in a Metal-Organic framework
(Wiley VCH Verlag, 2009-05)
[Yb(C4H4O4)15] undergoes a temperature-triggered single-crystal to single-crystal transformation. Thermal X-ray single-crystal studies showed a reversibly orchestrated rearrangement of the atoms generated by the ...
Crystal chemistry of organic minerals–salts of organic acids: the synthetic approach
(Taylor & Francis, 2018-07)
The term ‘organic minerals’ means naturally occurring crystalline organic compounds including metal salts of formic, acetic, citric, mellitic, methanesulfonic and oxalic acids. As for the rest of the (inorganic) minerals, ...
Kinetic Study of Seed-Assisted Crystallization of ZSM-5 Zeolite in an OSDA-Free System Using a Natural Aluminosilicate as Starting Source
(American Chemical Society, 2018-10)
We studied the crystallization of ZSM-5 zeolite by hydrothermal treatment in the absence of organic structure directing agents (OSDA) at 170, 180, and 190 °C, using Perlite as a natural source of SiO2 and Al2O3. Experimental ...
Why lamivudine assembles into double-stranded helices in crystals: Salt heterosynthon: Versus base-pairing homosynthon
(Royal Society of Chemistry, 2018-09)
Here we were interested in obtaining a better understanding of the competition between the salt heterosynthon and the base-pairing homosynthon formed by the anti-HIV drug lamivudine in the presence of strong acids. Even ...
Effect of ceria on the organization and bio-ability of anatase fullerene-like crystals
(Royal Socie, 2015-01)
The nanostructure and the oxygen storage capacity against reactive oxygen species (ROS) are essential features to take into account during the design of a new material that will be used as the basis of novel therapeutic ...
Significant progress in predicting the crystal structures of small organic molecules - A report on the fourth blind test
(Wiley Blackwell Publishing, Inc, 2009-02)
We report on the organization and outcome of the fourth blind test of crystal structure prediction, an international collaborative project organized to evaluate the present state in computational methods of predicting the ...
